Hi

A curious case about voodoohda: I have success on 10.9.2 with acer notebook with first gen intel hd graphics. Unfortunately, voodoohda fail. I have 2 or 3 seconds of audio playback and “puff”, no audio. I try all versions and variants of voodooHDA. No solution! Please, anyone have idea about whats goin on?

Confirmed. I changed my vanilla installation by Niresh 10.9 and audio works perfectly before installing kexts intelHDGraphics. After, no audio. Is confirmed for me that intelHDGraphics driver interferes with voodooHDA.

Did you have any progress with this? i have the same problem right now in Yosemite 10.10.1 with VoodooHDA 2.8.7 on my Emachines E732ZG laptop with AMD Mobility HD 5470 graphics and the same ALC272 audio codec.
Right after startup sound works, but only for ~3 seconds, then it dies. Changing the audiodevice in system settings solves the problem for the next 3 seconds, same as changing midi settings.
Another interesting thing: the lower the midi sample rate, the longer the sound works. I've tried various versions of voodoohda, if the sound devices appear in system settings the result is allways the same
